I trust no one, not even myself

Trust issues are pretty common:

“You believe lies so you eventually learn to trust no one but yourself.”
― Marilyn Monroe

“I trust no one, not even myself.”
― Joseph Stalin

“Don’t believe your neighbor or trust your friend. Be careful what you say even to your husband or wife. In these times sons treat their fathers like fools, daughters oppose their mothers, and young women quarrel with their mothers-in-law; your enemies are the members of your own family.”
― Micah 7
